Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen eines ebenen Reibringes, bestehend aus einem Tragring und aus einem auf wenigstens einer Tragringseite vorgesehenen, zumindest angenähert radiale Ölnuten bildenden Reibbelag, der zunächst aus einer Reibbelagbahn mit von zumindest einer Umfangsseite ausgehenden Schlitzen für die späteren Ölnuten ausgeschnitten und dann auf den Tragring aufgeklebt wird.The invention relates to a method for producing a flat Friction rings, consisting of a support ring and one on at least one Support ring side provided, at least approximately radial oil grooves Friction lining, which initially consists of a friction lining web with at least one Cut out circumferential outgoing slots for the later oil grooves and then glued to the support ring.

Zum Herstellen ebener Reibringe ist es bekannt (EP 0 305 582 A1), den Reibbelag als in sich geschlossenen Ring mit den die späteren Ölnuten bildenden Schlitzen aus einer Reibbelagbahn auszustanzen, die nach Papiermachart aus einem organischen Reibwerkstoff hergestellt wird, und diesen Reibbelagring auf den Tragring aufzukleben. Das Ausschneiden eines in sich geschlossenen Reibbelagringes, der bereits die Schlitze für die späteren Ölnuten aufweist, stellt zwar wegen der einfachen Handhabung einen geringen Herstellungsaufwand sicher, doch ergibt sich aufgrund der Ringform der Reibbeläge ein hoher Abfall an der Reibbelagbahn und damit eine unbefriedigende Materialausnützung. Wird der Reibbelag nach einem anderen bekannten Herstellungsverfrahren (EP 0 583 516 Al) aus einzelnen Reibbelagsektoren aufgebaut, die von einem Reibbelagstreifen abgeschnitten und mit gegenseitigem Abstand auf den Tragring aufgeklebt werden, um zwischen benachbarten Reibbelagsektoren radiale Ölnuten zu erhalten, so ergibt sich eine gute Materialausnützung für den Reibbelag, allerdings mit dem erheblichen Nachteil einer aufwendigen Herstellung, weil die einzelnen nicht zusammenhängenden Reibbelagsektoren vor dem Aufkleben auf den Tragring entsprechend positioniert werden müssen. It is known (EP 0 305 582 A1) to produce flat friction rings, the friction lining as a self-contained ring with the later oil grooves Punch slots out of a friction lining sheet, made according to paper making an organic friction material is made, and this friction lining stick on the support ring. Cutting out a self-contained Friction lining ring, which already has the slots for the subsequent oil grooves because of the simple handling a low manufacturing effort sure, but due to the ring shape of the friction linings there is a high drop on the friction lining track and thus an unsatisfactory use of material. Becomes the friction lining according to another known manufacturing process (EP 0 583 516 Al) made up of individual friction lining sectors, that of a friction lining strip cut off and glued to the support ring at a mutual distance to create radial oil grooves between adjacent friction lining sectors received, there is good material utilization for the friction lining, however with the considerable disadvantage of an expensive production because the individual non-contiguous friction lining sectors before sticking on the support ring must be positioned accordingly.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren zum Herstellen eines ebenen Reibringes der eingangs geschilderten Art so zu verbessern, daß eine einfache, wenig aufwendige Handhabung des Reibbelages mit einer guten Materialausnützung verbunden werden kann.The invention is therefore based on the object of a method for producing to improve a flat friction ring of the type described above in such a way that simple, inexpensive handling of the friction lining with good Material utilization can be combined.

Die Erfindung löst die gestellte Ausgabe dadurch, daß der Reibbelag in Form eines Streifens aus der Reibbelagbahn ausgeschnitten und im Bereich der Verbindungsstege zwischen den durch die Schlitze voneinander getrennten Reibbelagsektoren polygonartig zu einem Ring gebogen und auf den Tragring aufgeklebt wird.The invention solves the issue posed in that the friction lining in shape a strip cut out of the friction lining and in the area of Crosspieces between those separated by the slots Friction lining sectors bent like a polygon into a ring and onto the support ring is stuck on.

Durch das Ausschneiden von Reibbelagstreifen aus der Reibbelagbahn kann eine gute Materialausnützung der Materialbahn sichergestellt werden, weil ja zumindest bei einem geraden Streifenverlauf die einzelnen Streifen so nebeneinandergereiht werden können, daß jeweils der Längsrand, der die spätere äußere Umfangsseite des Reibbelages bildet, an dem die spätere innere Umfangsseite bildenden Längsrand anliegt. Wird ein gebogener Streifenverlauf gewählt, was bei einer Forderung nach einer beschränkten Anzahl von Reibbelagsektoren im Zusammenhang mit einer begrenzten Schlitzbreite wegen des durch die Schlitzausbildung vorgegebenen maximal möglichen Biegewinkels zwischen den Reibbelagsektoren notwendig werden kann, so beschränkt sich der anfallende Abfall auf die Schlitze und den sich zwischen den gebogenen Reibbelagstreifen ergebenen Zwickelbereich. Da die Reibbelagsektoren durch die die späteren Olnuten bildenden Schlitze bis auf einen verbleibenden Verbindungssteg voneinander getrennt sind, der eine Gelenkverbindung zwischen den Reibbelagsektoren ermöglicht, können die vorzugsweise durch ein Stanzen ausgeschnittenen Reibbelagstreifen ohne weiteres jeweils zu einem Polygonring gebogen werden. der auf einen entsprechenden Tragring aufgeklebt werden kann. Wegen der zusammenhängenden Reibbelagsektoren ergibt sich eine einfache Handhabung, was eine wenig aufwendige Herstellung bei einer guten Materialausnutzung erlaubt. Die Abweichung des Polygonringes von der Kreisform spielt für die Funktion des Reibringes keine Rolle, zumal die Reibbelagsektoren im Bereich ihrer Längsränder entlang von Kreisbögen ausgeschnitten werden können, die an den Außen- bzw. Innendurchmesser des Tragringes angepaßt sind.By cutting out friction lining strips from the friction lining web good material utilization of the material web can be ensured because yes at least in the case of a straight strip, the individual strips are lined up in this way can be that the longitudinal edge, which is the later outer Forms the peripheral side of the friction lining on which the later inner peripheral side forming longitudinal edge. If a curved stripe is chosen, what in the case of a demand for a limited number of friction lining sectors in Relation to a limited slot width because of the slot formation predetermined maximum possible bending angle between the Friction lining sectors may be necessary, so the accumulating is limited Waste on the slots and between the curved friction lining strips resulting gusset area. Since the friction lining sectors by the later Slots forming ol grooves apart from one another to a remaining connecting web are separated, the hinge connection between the friction lining sectors enables, the preferably cut out by punching Friction lining strips easily bent into a polygon ring become. which can be glued to a corresponding support ring. Because of the connected friction lining sectors are easy to use, which is a less complex production with good material utilization allowed. The deviation of the polygon ring from the circular shape plays for the Function of the friction ring does not matter, especially since the friction lining sectors in the area their longitudinal edges can be cut out along arcs that are adapted to the outer or inner diameter of the support ring.

Unterschiedliche Kreisbogenradien im Bereich der Außen- und der Innenumfangsseite bedingen allerdings einen geringfügigen Abfall aufgrund der sich zwischen den aneinanderstoßenden Außen- und Innenseiten der Reibbelagstreifen ergebenden Zwickel. Um einen solchen, wenn auch vergleichsweise geringen Abfall zu vermeiden, können die sich zwischen den Schlitzen ergebenden Reibbelagsektoren der Reibbelagstreifen auf der Außen- und Innenumfangsseite entlang von übereinstimmenden Kreisbögen ausgeschnitten werden. Die dadurch bedingten Abweichungen gegenüber dem Außen- bzw. Innenumfang des Tragringes sind für die Wirkungsweise des fertigen Reibringes unerheblich.Different arc radii in the area of the outer and inner circumferential side however cause a slight drop due to the between the abutting outer and inner sides of the friction lining strips resulting gusset. For such, albeit comparably To avoid small waste, the resulting between the slots Friction lining sectors of the friction lining strips on the outer and inner circumferential side cut out along matching arcs. The resulting deviations from the outer or inner circumference of the support ring are for the operation of the finished friction ring irrelevant.

Besonders vorteilhafte Herstellungsbedingungen ergeben sich in weiterer Ausbildung der Erfindung dann, wenn auf die dem Tragring zugekehrte Seite der Reibbelagbahn vor dem Ausschneiden des Reibbelagstreifens eine doppelseitig wirksame Klebefolie aufgeklebt wird, mit deren Hilfe der Reibbelag nach dem Ausschneiden auf den Tragring aufgeklebt werden kann. Durch diese beidseitige Klebefolie wird nicht nur das Aufkleben des aus der Reibbelagbahn ausgeschnittenen Reibbelagstreifens auf den Tragring erleichtert, sondern auch eine Verstärkung der Reibbelagstreifen im Bereich der Verbindungsstege zwischen den Reibbelagsektoren erreicht, so daß diese Verbindungsstege in einer für das Biegen innerhalb der Belagebene vorteilhaften Art ausreichend schmal ausfallen können, ohne den Zusammenhang der Reibbelagsektoren während der Handhabung der Reibbelagstreifen zu gefährden.Particularly advantageous manufacturing conditions result in others Formation of the invention when on the side facing the support ring Double-sided friction lining sheet before cutting out the friction lining strip effective adhesive film is stuck on, with the help of the friction lining after Cut out can be glued to the support ring. Through this bilateral Adhesive film is not only used to stick the cut out of the friction lining Friction lining strip relieved on the support ring, but also one Reinforcement of the friction lining strips in the area of the connecting webs between reached the friction lining sectors, so that these connecting webs in one for the Bending within the covering plane of the advantageous type is sufficiently narrow can without the connection of the friction lining sectors during handling endanger the friction lining strip.

Beim polygonartien Biegen der ausgeschnittenen Reibbelagstreifen stellen sich im Außenbereich der Verbindungsstege Zugkräfte und im Innenbereich Druckkräfte ein, was unter Umständen die Gefahr eines Auffaltens dieser Verbindungsstege aus der Reibbelagebene mit sich bringt. Um dadurch bedingte Nachteile zu vermeiden, kann der Reibbelag durch ein Warmpressen auf den Tragring aufgeklebt werden, so daß die im Bereich der Verbindungsstege auf die Reibbelagstreifen ausgeübten Andrückkräfte an den Tragring ein solches Auffalten mit Sicherheit unterbinden.When cutting out the friction lining strips cut out polygonally tensile forces in the outer area of the connecting webs and compressive forces in the inner area a, which may create the risk of unfolding these connecting webs from the friction lining level. To be contingent To avoid disadvantages, the friction lining can be hot-pressed onto the Support ring are glued so that in the area of the connecting webs the friction lining strips exerted pressure forces on the support ring such Prevent unfolding with certainty.

Der dargestellte Reibring besteht aus einem stählernen Tragring 1, der beidseitig mit einem Reibbelag 2 versehen ist. Dieser Reibbelag 2, der beispielsweise aus einem nach Papierart hergestellten, organischen Reibwerkstoff gebildet wird, weist einzelne, sich zwischen radialen Ölnuten 3 ergebende Reibbelagsektoren 4 auf. Gemäß dem Ausführungsbeispiel werden diese Ölnuten 3 durch abwechselnd von der inneren und der äußeren Umfangsseite ausgehende Schlitze 5 gebildet. die sich bis auf einen schmalen Verbindungssteg 6 zwischen den Reibbelagsektoren 4 über die Breite des Reibbelages 2 erstrecken. Die von der Innenumfangsseite ausgehenden Olnuten 3 bringen den Vorteil mit sich, daß das der Fliehkraft unterworfene Öl in diesen Ölnuten 3 gestaut wird und das Trennen von aneinanderliegenden Reibringen unterstützt.The friction ring shown consists of a steel support ring 1 on both sides is provided with a friction lining 2. This friction lining 2, for example formed from an organic friction material produced according to the type of paper is, has individual, between radial oil grooves 3 resulting friction lining sectors 4 on. According to the embodiment, these oil grooves 3 through alternating from the inner and the outer peripheral side Slits 5 formed. except for a narrow connecting bridge 6 between the friction lining sectors 4 extend across the width of the friction lining 2. The of the inner circumferential side outgoing oil grooves 3 have the advantage that the oil subjected to centrifugal force is stowed in these oil grooves 3 and that Separation of adjacent friction rings is supported.

Zur Herstellung des beschriebenen Reibringes wird auf den Tragring 1 ein Reibbelag 2 aufgeklebt. Zu diesem Zweck werden aus einer entsprechenden Reibbelagbahn Reibbelagstreifen 7 ausgestanzt, die nebeneinandergereiht sind und abwechselnd von den beiden Längsseiten ausgehende Schlitze 5 aufweisen. Da diese Reibbelagstreifen 7 einen übereinstimmenden Längsrandverlauf auf beiden Seiten zeigen, schließen sie abstandslos aneinander an, so daß beim Ausstanzen dieser Reibbelagstreifen 7 lediglich in den Schlitzbereichen Abfälle anfallen. Wie den Fig. 3 und 4 entnommen werden kann, sind die Reibbelagsektoren 4 zwischen den Schlitzen 5 durch übereinstimmende Kreisbögen begrenzt, so daß nach einem polygonartigen Biegen der Randstreifen über die sich im Bereich der Schlitze 5 ergebenden Verbindungsstege 6 ringförmige Reibbeläge 2 erhalten werden, die entsprechend den Fig. 1 und 2 auf einen Tragring 1 aufgeklebt werden können. Bei der Ausbildung der Schlitze 5 ist naturgemäß der spätere Biegewinkel zwischen den Reibbelagsektoren 4 zu berücksichtigen, um den die Flanken der Schlitze 5 gegenüber ihrem späteren Verlauf im Bereich der Reibbelagstreifen 7 abweichen müssen. Dies bedeutet bei den vom Außenumfang ausgehenden Schlitzen 5 eine Materialeinsparung.To produce the friction ring described, a support ring 1 is used Friction lining 2 glued on. For this purpose, a corresponding Friction lining track 7, which are lined up next to one another, are punched out and alternately have slots 5 extending from the two long sides. Since this friction lining strip 7 has a matching longitudinal edge course show on both sides, connect to each other without any gap, so that when punching out these friction lining strips 7 only in the slot areas Waste. 3 and 4 can be seen, are Friction lining sectors 4 between the slots 5 by matching circular arcs limited, so that after a polygonal bending of the edge strips About the resulting in the region of the slots 5 connecting webs 6 ring-shaped Friction linings 2 are obtained, which correspond to FIGS. 1 and 2 a support ring 1 can be glued on. When forming the slots 5 is naturally the later bending angle between the friction lining sectors 4 too take into account the flanks of the slots 5 compared to their later The course in the area of the friction lining strips 7 must deviate. this means material savings in the slots 5 extending from the outer circumference.

Zum Aufkleben der zu einem Ring polygonartig gebogenen Reibbelagstreifen 7 könnten der Tragring 1 und/oder die Reibbelagstreifen 7 mit einer Klebeschicht versehen werden. Besonders einfache Verhältnisse werden allerdings mit einer doppelseitig wirkenden Klebefolie 8 erhalten, die zunächst auf die Reibbelagbahn aufgebracht wird, aus der dann die Reibbelagstreifen 7 ausgeschnitten werden. Zum beidseitigen Bekleben eines Tragringes 1 mit solchen Reibbelagstreifen 7 braucht zunächst lediglich ein Reibbelagstreifen 7 mit nach oben weisender Klebefolie 8 in eine entsprechende Form 9 eingelegt zu werden, wie sie in der Fig. 2 strichpunktiert angedeutet ist, bevor der Tragring 1 auf diesen in der Form 9 in einer Ringform gehaltenen Reibbelagstreifen 7 aufgelegt und mit einem weiteren Belagstreifen 7 abgedeckt wird, der durch die Form 9 ebenfalls in die an den Tragring 1 angepaßte Ringform gezwungen wird. Danach kann die Form 9 durch einen Deckel 10 verschlossen und der Reibring unter Druckanwendung erwärmt werden, bis die Klebung über die Klebefolien 8 ausgehärtet ist.For gluing on the friction lining strips 7, which are bent polygonally into a ring could the support ring 1 and / or the friction lining strip 7 with an adhesive layer be provided. However, particularly simple relationships with a get double-sided adhesive film 8, initially on the friction lining is applied, from which the friction lining strips 7 are then cut out become. For gluing a support ring 1 on both sides with such friction lining strips 7 initially only needs a friction lining strip 7 with upwards pointing adhesive film 8 to be inserted into a corresponding mold 9, such as it is indicated by dash-dotted lines in Fig. 2 before the support ring 1 on this placed in the form 9 in a ring-shaped friction lining strip 7 and is covered with a further covering strip 7, which is formed by the shape 9 is also forced into the ring shape adapted to the support ring 1. After that the form 9 can be closed by a cover 10 and the friction ring be heated under pressure until the adhesive over the adhesive films 8th is cured.

  2. A method according to claim 1, characterised in that the sectors of the friction lining strip obtained between the slots are cut out on the outer and inner periphery side along coinciding circular arcs.
  3. A method according to claim 1 or 2, characterised in that before the strip of friction lining is cut out, an adhesive foil active on both sides is stuck to the side of the web of friction lining facing the supporting ring and is used to stick the friction lining to the supporting ring after cutting out.
  4. A method according to any of claims 1 to 3, characterised in that the friction lining is stuck on the supporting ring by hot pressing.
